LATHING STRIP.

Application filed August 10, 1922. Serial No. 580,927.

To all whom it may concern:

Be it known that I, FRED M. SPAYD, a citizen of the United States,residing at Van Wert, in the county of Van VVert and State of Ohio, haveinvented certain new and useful improvements in Lathing Strips; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to an improved lathing strip and one object ofthe invention is to provide a lathinp' strip in which there may beprovided a backing strip of card board or other suitable material andlaths extending transversely of the backing strip, ccrtain'of the lathshaving their ends terminating within the confines of the backing stripand serving to prevent bending or the strip and the other lathsextending beyond one side of the backing strip for extending inoverlapping relation to the backing strip oil a second lathing strip.

Another object of the invention is to provide'a lathing strip in whichthe laths which extend beyond the side edge of the backing strip willhave their inner ends terminating adjacent the transverse center of thebacking strip, the lathe being slightly shorter than the width of thebacking strip so that when two of the lathing strips are put in placewith the extended laths overlapping the adjacent strip, the endportionsof the laths of the two strips will not con tact.

Another object of the invention to so construct the lath strips thatwhen the lath strips are put in place with the side edges of adjacentstrips contactin the ends out the laths ill be out of contact and thuspermit expansion and contraction.

Another object of the invention is to so construct these lathing stripsthat when put in place, the laths of adjacent strips which extend inoverlapping relation will serve as bracing means, to prevent the lathshaving any movement which might tend to cause cracking o1 the plaster orstucco.

Another object of the invention is to so construct the laths used thatwhen viewed in cross section, they w1ll be provided with head forminortions and reduced neck 3 g forming portions, the neck forming portionsen 'a 111 the baclnn strm and the b 2:) V b 1.

space between the laths being. thus formed into pockets having enlargedinner portions and reduced inlets between the laths, thus preventing themortar or other plastic from having any movement after the laths shrinkin drying.

This invention is illustrated in the accompanying drawings, wherein:

Figure l is a View in front elevation showing two strips of lathingstrips in place.

Figure 2 is a perspective view showing a portion of a lathing strip anda fragment of a second in into operative relation to the first lathingstrip.

Figure 3 is a fragmentary lon itudinal sectional View taken along theline 3-3 oi Fig. 1.

Figure & is a fragmentary sectional taken along the line 4l of Fig. l.

The lathing strips will be formed of a suitable width according towhether it is desired to have each strip bridge three of the joists orstuddings 1 as shown in Fig. 1, or may be formed wider if it is desiredto have the strips bridge a greater number of these studdings. Thelathing strips may be of any desired length and when not in use will berolled. l/Vhen it is in use, the strip will be cut the desired length sothat it will reach from the top to the bottom of the space to beplastered or stuccoed. This lathing strip is provided with a backingstrip 2 which may be formed of cardboard or any other suitable material.ing strip will be coated vith tar or any other suitable material shownat 3 and the laths l will be put in place as shown. These laths will inthe pref rred form be arranged in groups which have been designated bythe letters A and B. The laths of the group A extend across the backingstrip from one side to the other but terminate in slight spaced relationto the side edges of the backing strip so that when the lathing stripsare put in place against the studding, the ends of the laths 4 willterminate in spaced relation as shown clearly inFig. 3. Therefore, thelaths may expand and contract without danger of having their endscontact and cause bulging. The laths of the group B are of the samelength as the laths of the group A and these laths are put in placeshown in Fig. 2 with their inner ends terminating adjacent thetransverse center of the back- View position for moving Thisbackplaster.

ing strip. These laths extend beyond the side of the backlng StI'lP sothat when the strips are put in place and secured to the studding theextended end portions of the laths of the group B will extend inoverlapping relation to the adjoining lathing strip between the laths ofthe groups A and terminate in slight spaced relation to the inner endsof the lathe of the group B of this lat-hing strip. By having the lathsoi the adjoining strip extending in overlapping relation, the strip willbe prevented from being twisted out of shape and further driven to causethe securing nails to he driven into the studding asshown in Fig. 3.When the latlnng is used for holding plaster or stucco, the plastic isforced in between the laths i and if a backing is not used, a great deal01" the plaster or stucco has a tendency to fall down behind the lathingstrips. The backing pr vents this and thus prevents-a great waste ofplaster and stucco.

In order to provide a means for holding a body of plaster or stuccotightly in place after'drying, or in order to prevent the body ofplaster or stucco. from becoming loose froiii the laths after the lathshave shrunk incidental to the drying of the plaster or stucco, the innerportions of the side edges ot the laths t :are cut away to term in--wardly facing shoulders. These shoulders are arranged in parallelrelation 'to the I outer faces of the laths 4;, as shown in Fig.

l, so that as the laths shrink in the direction of their widta as anincident to the drying or tne plaster or stucco, these shoul ders willhold the hody of the plaster or stucco tightly and will prevent it frobecoming loose. The laths 4i are there'lore applicable not only tohacking s-tripsuch as the strip :2 shown in the drawings, but may alsohe nailed-directly to any flat surface to which plaster or stucco is tobe applied. "When the laths are not to be secured. to a backing strip,such as the strip 1 shown in the drawings, but are to he applied to aflat surface, they may be applied directly to such surface, no meansbeing necessary to space the lathe from the s irface in order to permitthem to firmly hold the mass of plaster or stucco.

There has thus been-provided strips of lathing which can be very easilyand quickly put in place and the securing nails for the laths readilydriven into the proper portions .01 the laths for enteringthe-studdings. Y

I claim: I 1

1. A lathing strip comprising a backing strip and spaced laths carriedby and all extending transversely of the backing strip, certain of saidlaths' extending beyond the backing strip at one side thereof and having their inner ends tern'iinating intermediate the width of the backingstrip, there- .by leaving portions of said backing strip unoccupied bylaths, and the remaining laths'having their ends terminating within theconfines ofthe backing strip.

2. A lathing strip comprising a backing sheet, groups of laths' allextending transversely of said backing sheet, the laths of certain ofsaid groups extending beyond one side of said backing strip and havingtheir .inner ends terminating intermediate the width of the 'baclningstrip, thereby le-avingportions of said backing strip unoccupied bylaths, and the laths of the other groups having their ends terminatingin slight spaced relation to the side ed es oil? the backing strip. V

3. The structure oi claim 1 having the extended laths alternated be weenthe laths terminating withinthe confines of the back- 7 ing strip. v r

In testin'iony whereof I have hereunto ate fixed my signature, v
